How Installing Energy-Efficient Windows in New York City Saves You Money

When you switch to energy-efficient windows, you may see some benefits, such as:

• Save on electricity bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% since you need less energy.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
• Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, particularly if you have an older home.
• Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can lower your carbon footprint by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in New York City

When considering window installation, each company offers different services and prices. Let’s go over some average costs and services.

How Much Do New Windows Cost?

Typically, homeowners in New York City can expect that most window installations will range from $250 to $1,200, with the average cost sitting at around $600. These estimates are based on specific characteristics of your installation, like number of windows, material, size, the location of your home, type and more.

It’s also worth keeping in mind that energy-efficient windows will cost more upfront, but Energy Star estimates that upgrading the windows on your New York City home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you’ll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Asking for free quotes from several installers is the best way to figure out which one is right for you.

What Services do Window Installers Offer?

In general, there are two kinds of window installation services companies provide: full-frame and pocket installations.

A full-frame installation is a replacement of the full window. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve other materials, like insulation and drip edges, which increase the overall cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. Pocket installations are simpler and won’t cost as much because they entail merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you may need a full-frame installation instead.

Your window installation company can help you choose which type of installation you should get.

How We Choose the Best Window Installers in New York City

EcoWatch reviews are different from most reviews, as we’re examining these companies through a sustainability lens. Along with energy efficiency, we analyzed several window installers in New York City and assigned rankings based on the following methodology:

Service Area

Because this is a guide for New York City, we only included companies that cover the city. There are other reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in New York City.

Work Quality

When selecting new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand of window you opt for. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent online reviews to determine the companies with the most consistent customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including warranty, quality of parts, cost, professionalism, quality of installation and more.

Cost

This one is a give-and-take: as with most services, cheap window companies won’t always provide the highest quality service. On the other hand, we want to make sure we’re highlighting companies that offer a range of price and financing options so they’re accessible to most homeowners.

Warranty

Protecting your investment in new windows is important. That’s why window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Due to New York City’s climate, homeowners will want to mitigate low efficiency, water damage and rot. We factored in local experience to reflect the ability of New York City window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
